Introduction
The TCA9406 is a 2-bit bidirectional I²C and SMBus voltage-level translator with an output enable (OE) input. It is operational from 1.65 V to 3.6 V on the A side, referenced to VCCA, and from 2.3 V to 5.5 V on the B side, referenced to VCCB. This allows the device to interface between lower and higher logic signal levels at any of the typical 1.8-V, 2.5-V, 3.3-V, and 5-V supply rails. The OE input pin is referenced to VCCA, can be tied directly to VCCA, but it is also 5.5-V tolerant. The OE pin can also be controlled and set to a logic low to place all the SCL and SDA pins in a high-impedance state, which significantly reduces the quiescent current consumption. Under normal I²C and SMBus operation or other open-drain configurations, the TCA9406 can support up to 2 Mbps; therefore, it is compatible with standard I²C speeds where the frequency of SCL is 100 kHz (Standard-mode), 400 kHz (Fast-mode), or 1 MHz (Fast-mode Plus). The device can also be used as a general purpose level translator, and when the A- and B-side ports are both driven with push-pull devices the TCA9406 can support up to 24 Mbps. The TCA9406 features internal 10-kΩ pullup resistors on SCL_A, SDA_A, SCL_B, and SDA_B. Additional external pullup resistors can be added to the bus to reduce the total pullup resistance and speed up rising edges.
Features
- 2-Bit Bidirectional Translator for SDA and SCL Lines in I²C Applications
- Provides Bidirectional Voltage Translation With No Direction Pin
- High-Impedance Output SCL_A, SDA_A, SCL_B, SDA_B Pins When OE = Low or VCC = 0 V
- Internal 10-kΩ Pullup Resistor on All SDA and SCL Pins
- 1.65 V to 3.6 V on A port and 2.3 V to 5.5 V on B port (VCCA ≤ VCCB)
- VCC Isolation Feature: If Either VCC Input Is at GND, Both Ports Are in the High-Impedance State
- No Power-Supply Sequencing Required: Either VCCA or VCCB Can Be Ramped First
- Low Ioff of 2 μA When Either VCCA or VCCB = 0 V
- OE Input Can Be Tied Directly to VCCA Or Controlled By GPIO
- Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II
- ESD Protection Exceeds JESD 22
- A Port – 2500-V Human-Body Model (A114-B) 250-V Machine Model (A115-A) 1500-V Charged-Device Model (C101)
- B Port – 8-kV Human-Body Model (A114-B) 250-V Machine Model (A115-A) 1500-V Charged-Device Model (C101)
